NATO's Jens Stoltenberg will meet with the German chancellor to discuss proposal to send more troops to Afghanistan.

Afghan Voice Agency(AVA), A proposal to boost NATO forces in Afghanistan will be on the agenda of a meeting between the alliance Secretary-General Jens Stoltenberg and German Chancellor Angela Merkel on Thursday.

The meeting comes on the heels of a request from military chiefs for more troops to be sent to Afghanistan.

On Wednesday, Stoltenberg met British Prime Minister Theresa May, a day after reports suggested NATO had asked Britain for more troops a few weeks ago

He confirmed he had received a request for more troops, but insisted it would not mean a return to combat operations.

"We have received a request from our military authorities to increase our military presence in Afghanistan with a few thousand troops," Stoltenberg said.

"It will continue to be a train, assist and advise operation," he added.

Stoltenberg said a decision on the request will be made within weeks and the issue is expected to be high on the agenda at the NATO annual summit in Brussels on May 25.

Al Jazeera reporting from Berlin, said Merkel is likely to say Germany supports the role of foreign troops in Afghanistan, but "the question will be whether her government will commit more troops."

Desperate' for assistance

Since NATO's combat mission in Afghanistan formally ended in 2014, Taliban attacks have intensified and Afghan military and civilian casualties have risen. NATO already has some 13,450 troops in Afghanistan, including around 6,900 US and 500 British military personnel, who are training the Afghan armed forces to eventually take over the country's defence and security.

The US has an additional 1,500 soldiers conducting assist missions directly under Pentagon command.

They have faced high casualties, up 35 percent in 2016 with 6,800 soldiers and police killed, according to a US watchdog.

In April, the Taliban announced the beginning of its annual "spring offensive" and last week the armed group stormed and seized a district in the vicinity of Kunduz, in northern Afghanistan.

Al Jazeera's John Hendren, reporting from Kabul, said the Afghan government is in "desperate" need of assistance.

"If you talk to Afghan troops, they say they desperately need the help," Hendren said. "In the north and south of the country, they are embattled."

He added that the goal of the idea of a troops increase is to get the Taliban to the negotiating table.
